Abstract

The present invention relates to a wideband antenna that uses coupling matching. The antenna comprises: a 1st conductive member electrically coupled to the ground; a 2nd conductive member electrically coupled to a feed point, the 2nd conductive member being formed in parallel to the 1st conductive member with a predetermined distance therebetween; and a 3rd conductive member for radiating an RF signal, the 3rd conductive member being extended from the 1st conductive member, wherein the 1st and 2nd conductive members have a predetermined length to generate a travelling wave and to ensure sufficient coupling. The disclosed antenna is advantageous in that it can provide a multiband internal antenna having wideband characteristics by making use of coupling matching during the design of multiband.

Description

technical field [0001] The present invention relates to an antenna, in particular to an antenna supporting broadband impedance matching. Background technique [0002] Currently, with the reduction in size and weight of mobile communication terminals, the function of enjoying mobile communication services of various frequency bands through one terminal is required. For example, currently required terminals need to be able to simultaneously use signals of multiple bandwidths in mobile communication services using multiple bandwidths according to requirements. This kind of multi-band accommodation requires antennas with broadband characteristics. Communication services include: CDMA services with a bandwidth of 824-894MHz and PCS services with a bandwidth of 1750-1870MHz commercially available in Korea; CDMA services with a bandwidth of 832-925MHz commercially available in Japan; PCS services with a bandwidth of 1850-1990MHz commercially available in the United States services...
